I get massive twitches in the side of my stomach quite frequently. They are totally different to the normal little ones I get everywhere else. These ones are really visable, you can see my whole side moving! The first time I had them they lasted for hours, it totally freaked me out. Now I find them quite amusing.
Try not to worry about it, I'm sure they are completely harmless.

the stomach twitches are normal and a LOT of BFS'ers report having them. I get them from time to time too. There were a coupld of ladies on this forum several months ago talking about how their stomach twitches felt like a baby kicking when they were pregnant. I'm glad that's the only thing I get to feel the pregnant ladies feel. Although with my beer belly, you'd think I WAS pregnant! Hey, don't laugh! It took a LOT of beer to get this physique, more $ spent on beer than most people spend on the gym and who want a dog gone six pack anyway. heck, I;ve got the whole darn KEG!
